- The AMS Certified Broadcast Meteorologist written test is scheduled after your AMS application, not on a fixed seasonal calendar.
- The written exam is 100 multiple-choice/true-false questions with a 75% passing score; confirm the time limit on your appointment.
- Each scheduling attempt adds a testing fee: $60 remote, $75 US center, or $85 international, on top of the application fee.
- Two separate weathercasts (5 minutes max each) are evaluated independently of your written-test date.
Why the CBM Has No Fixed Exam Calendar
If you came here looking for a list of 2026 test dates with registration cutoffs, here is the most useful thing to know first: the Certified Broadcast Meteorologist credential from the American Meteorological Society (AMS) does not publish a fixed calendar of national exam days that we could verify. Instead, the written test is delivered through a third-party testing provider, and you pick an appointment after AMS approves your application. The current provider is SMT/Prometric, although an older AMS FAQ still refers to PSI, so always trust the instructions in your approval message over any archived page.
That distinction matters for planning. With a fixed-date exam, you work backward from a single national day. With the CBM, you work backward from an appointment you choose yourself, which gives you flexibility but also removes the external deadline that keeps many candidates honest. Without a hard date on the calendar, it is easy to let preparation drift for months.
Two Tracks, Two Clocks: Written Test and Weathercasts
The CBM is not a single-event exam. Candidates satisfy two distinct components, and each runs on its own timeline.
| Component | What it involves | Timing driver |
|---|---|---|
| Written test | 100 multiple-choice/true-false questions, closed book, 75% to pass | Appointment you schedule through the testing provider after AMS approval |
| Weathercast evaluation | Two additional weathercasts, active and routine, maximum 5 minutes each | Your own submission readiness |
For the weathercast portion, reviewers require an average above 3.0 separately in Graphical Content, Explanation, and Presentation. Spanish-language submissions need an English transcript. Because these submissions are recordings you prepare, you control when they are ready. A sensible approach is to treat the written appointment and the weathercast submissions as parallel workstreams rather than sequential ones, so a delay in one does not stall the other.
One caution: the separate weathercast evaluation criteria are not written-test topic domains. Do not confuse presentation scoring with the content you will be tested on at the keyboard.

What Must Happen Before You Can Schedule
You apply through AMS first. Only after that step can you schedule your written test with the provider. That ordering is the real "deadline" structure of the credential: your earliest possible test date is gated by how quickly you assemble your application package.
The package depends on eligibility documents that can take time to gather:
- Education: an accredited meteorology or atmospheric-science degree, or an approved equivalent, with required coursework documented by transcripts.
- Experience: two years of full-time or three years of part-time on-air experience. Work at a student station is excluded.
- Application fee: $330 for AMS members or $660 for nonmembers.
Transcript requests are the most common source of delay because registrars operate on their own schedules, not yours. Request them early, before you decide on a target exam month. Our CBM Requirements guide walks through eligibility in more detail, and the CBM Certification Cost breakdown covers the fee structure.
Key Takeaway
Treat application approval as your real starting gun. Submit your AMS application and transcripts first, then choose an appointment window that leaves enough runway for focused preparation, rather than booking aspirationally and scrambling.
Scheduling Mechanics: Remote vs. Testing Center
Both remote and in-center delivery are available. Which you choose affects cost, logistics, and how much control you have over your environment.
| Option | Per-scheduling fee | First-attempt total (application + fee) | Considerations |
|---|---|---|---|
| Remote (member) | $60 | $390 | Home or office environment; confirm technical and room requirements |
| Remote (nonmember) | $60 | $720 | Same logistics; higher application fee |
| US testing center | $75 | Application fee plus $75 | Controlled setting; travel to a center |
| International testing center | $85 | Application fee plus $85 | Availability varies by location |
The remote first-attempt totals shown exclude AMS dues and your preparation costs. For broadcast meteorologists working irregular shifts, remote delivery can be attractive because it removes travel from the equation, but it places responsibility on you to meet the provider's environment rules. Review those requirements in your appointment confirmation, since calculator and adaptive-testing rules were not verified in the public sources we reviewed.
How Timing Interacts With Fees and Retakes
Because the testing fee is paid each time you schedule, your timing decisions have direct financial consequences. Every scheduling attempt carries its own $60, $75, or $85 charge depending on delivery mode. Rushing to the earliest available slot and then needing a second attempt costs you another scheduling fee, plus the opportunity cost of delay.
Public sources do not disclose current written-exam pass rates, so there is no reliable number to tell you how likely a retake is. A 2019 Board note estimated that about half of candidates passed the first weathercast evaluation, but that figure describes the weathercast component, not the written test, and it is not a current statistic. Our CBM Pass Rate article explains what is and is not known, and How Hard Is the CBM Exam? discusses difficulty in context.
The practical takeaway is to schedule when you are ready, not when you are merely eligible. If you want to gauge readiness before spending a scheduling fee, take timed sets on our CBM practice test platform and identify weak domains first.
Building a Backward Plan From Your Appointment
Once your application is approved and you have an appointment, you can plan backward. AMS publishes fifteen substantive subject headings in its written-test reference list, from General Meteorological Knowledge through Winter Weather. These are unweighted topics, not an official blueprint, and AMS publishes no topic percentages, so any allocation of study time is your own editorial judgment.
Here is one way to sequence the fifteen areas across a preparation window, tied to how the topics build on each other:
Foundations
- General Meteorological Knowledge and Physical Meteorology: thermodynamics, moisture, stability, and radiation fundamentals that every later topic leans on.
- Data & Instruments and Station Scientist: observation practices, instrument behavior, and the on-station role that is distinctive to broadcast work.
Large-scale dynamics and guidance
- Cyclones and Jets and Numerical Weather Prediction: how large-scale patterns drive forecasts and where model guidance is trustworthy or flawed.
- Climatology & Climate Change: background knowledge needed to speak accurately on the air.
Remote sensing and hazards
- Radar Meteorology and Satellite: product interpretation and limitations.
- Severe Storm Structure/Tornadoes, Flooding, and Tropical Meteorology: the high-consequence events viewers rely on you for.
Seasonal, regional, and public-facing topics
- Winter Weather, Regional Weather, and Weather Safety: communication-oriented material where precision of language matters.
- Full mixed review and timed practice across all fifteen areas.
The reasoning is simple: foundations first because radar, satellite, and severe-storm questions assume you already understand stability and moisture. Safety and regional topics go late because they are easier to review quickly once the physics is solid. For a fuller preparation framework, see our CBM Study Guide.
Why the order matters for broadcasters
Working meteorologists often feel strongest in Radar Meteorology, Severe Storm Structure/Tornadoes, and Weather Safety because they use those daily. The less visible risk areas tend to be topics like Numerical Weather Prediction fundamentals, Climatology & Climate Change, and Data & Instruments, where on-air habit does not substitute for textbook-level recall.
- Audit your weakest domains in the first week, not the last.
- Reserve your final stretch for mixed-domain timed sets rather than new material.
What to Reconfirm Before Exam Day
Several details in public sources are older or provider-specific, so reconfirm them against your actual appointment rather than relying on a blog post, including this one.
- Time limit: 120 minutes is stated in a legacy-provider official FAQ. Reconfirm with your current appointment.
- Question count: 100 multiple-choice/true-false questions. The split between scored and unscored items is not disclosed.
- Closed book: plan on no reference materials.
- Provider and check-in rules: follow SMT/Prometric instructions for identification, arrival, or remote proctoring setup.
- Calculator and adaptive rules: not verified in public sources, so ask or read your confirmation carefully.
The passing score is 75%. Our CBM Passing Score guide explains how to think about that target, and the one-page CBM Cheat Sheet is a handy final-week review aid.
After You Pass: Validity and Renewal Dates
Certification is valid for one year, so your passing date effectively sets your renewal calendar. Annual renewal costs $206 for members or $515 for nonmembers, and the credential also involves 28 professional-development points every five years. Mark both dates the day you receive your result, since lapsing creates avoidable hassle.
